SP ARK-PRODUCING TOY.

Application filed August 1, 1927, Serial No It has become known toproduce sparks by means of a cerium stone sliding or rotating on anemery disk, said sparks becoming then visible from the outer side inalternating colors through openings provided in the toy and havingseveral transparent plates. This arrangement is not suitable for toyswith transparent disks as too many operations are necessary and thecosts of manufacturing of the toy are too high. This inconvenience isavoided, according to the invention, in a simple and cheap manner. Thelever carrying the cerium stone and which either rotates or isstationary is extended and openings are arranged in the extension andclosed with colored transparent panes fixed by means of flaps. Thisarrangement is cheap and presents further the advantage that the sparksproduced strike very strongly onto the transparent panes as the leverand emery disk are close together, the sparks being atomized by thestriking against the. colored panes so that a splendid color effect isproduced.

In a second form of construction a colored transparent pane is fixed bymeans of a flap directly on one end of the lever which carries thecerium stone.

Two forms of construction of a lever carry ing the cerium stone areshown, by way of example, in the accompanying drawings, in

which Fig. 1 is a longitudinal section,

Fig. 2 a top plan view;

Fig, 3 shows in side elevation the lever of the second form ofconstruction.

Fig. 4 shows the improved lever in connection with a sp-mnmg top.

On a levera a cerium stone 1) 1s fixed WhlCll is in contact with anemery layer (1 on a disk 0. The lever a is, according to the invention,40 extended and has in its extended portion one or several openings 7.On the upper or lower surface 'of the lever a differently "coloredtransparent panes g are fixed to close said openings f. Flaps h of thelever a serve to 4 securely hold said transparent panes.

In the second form of construction a flap V i on one end of the lever aserves to securely hold a colored pane is when said flap is bent over sothat said colored pane is projects from the end of the lever and issecurely held on the same.

I claim 1. In a spark producing toy, in combination with an emery disk acerium-lever and cerium stones fixed on said lever so that they slide onthe emery disk, an extension at one end of said lever and havingapertures, flaps at thesides of said extension portion of said lever,and colored transparent panes placed over said openings and securelyheld in position by the-folded over flaps of said lever.

2. In a spark producing toy as specified in claim 1 a flap at the freeend of said lever, and a colored transparent pane held on said lever bythe folded over flap so that it projects from the end of said lever.

In testimony whereof I aifix my signature.

CARL ARNOLD.
